[0001] This application claims the benefit of Disclosure Document No. 477,905 filed Aug. 2, 2000, entitled “WATERHOPPER” which is hereby incorporated by reference herein in its entirety, including but not limited to those portions that specifically appear hereinafter.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0002] Not Applicable.

BACKGROUND OF THE INVENTION

[0003] 1. The Field of the Invention

[0004] The present invention relates generally to floating recreational devices, and more particularly, but not necessarily entirely, to a movable, floating modular playground configured to accommodate various playground equipment for kids of all ages.

[0005] 2. Description of Related Art

[0006] The prior art discloses a number of water trampolines. Water trampolines provide a leisure time activity for kids of all ages in a body of water. The combination of a trampoline and an inflatable vessel allows users to enjoy the bouncing and acrobatic activities performed on a trampoline with the benefits of playing in the water. However, the disclosed trampolines are limited to only one recreational device, the trampoline.

[0007] U.S. Pat. No. 6,223,673 granted to Mears et al. discloses a floatable park that includes a trampoline and a first inflatable object attached to the trampoline. Mears discloses attaching another recreational device to the trampoline, such as a giant inflatable pillow, an inflatable log or a slide. However, the park needs to be inflated with air and is only held together with straps.

[0008] The prior art also discloses a number of floating docks and decks. For example, U.S. Pat. No. 6,073,572 granted to Gruhn et al. discloses a floating dock. Gruhn discloses individual modular floating sections that can be connected together to form a floating structure. However, the prior art docks and decks are limited to a floating deck structure without additional attachments.

[0009] U.S. Pat. No. 5,823,132 granted to Donovan discloses a floating deck structure. Donovan discloses a structural deck that floats on a rigid, buoyant material filled watertight float. The deck can be configured to accommodate a variety of accessories and furnishings for various recreational activities. However, the invention is not modular in design and limited to a deck structure.

[0010] The prior art fails to disclose a rigid floating playground module which can be interconnected to other playgrounds. The disclosed playgrounds achieve their buoyancy with an inflatable member, which can be punctured and require patching or replacement.

[0011] The prior art is thus characterized by several disadvantages that are addressed by the present invention. The present invention minimizes, and in some aspects eliminates, the above-mentioned failures, and other problems, by utilizing the methods and structural features described herein.

[0014] It is a further object of the present invention, in accordance with one aspect thereof, to provide a floating playground which is sturdy and does not need to be inflated.

[0015] It is an additional object of the invention, in accordance with one aspect thereof, to provide a floating playground with a modular design, wherein the modular units can be securely connected with other units.

[0016] The above objects and others not specifically recited are realized in a specific illustrative embodiment of a floating playground. The floating playground includes two modules attached together. The modules are each supported by a floating vessel. The floating vessels are rectangular shaped, rotationally molded pontoons filled with foam. Preferably vertical posts attach to the frame that encircles the pontoons and are able to support the recreational implement. One of the modules comprises a lower deck beneath an upper deck. The upper deck has a railing which supports a slide, climbing net, a basket ball hoop and a ladder. The other module is a trampoline. The modules can also support a wide variety of other recreational implements including, but not limited to: a trampoline, a climbing net, a slide, a ladder, a basketball hoop, a deck, a swing, a bathroom, a kitchen, a canopy covering the top or sides of the deck, a tent, an infant swing, an inflatable plastic log, a toy captains wheel, a toy periscope, a glass bottom section, a set of monkey bars, a jungle gym, a climbing tube or any other recreational implement.

[0017] Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by the practice of the invention without undue experimentation.

[0047] Applicant has discovered that floating playgrounds are more versatile and provide more recreation if the playground is movable and modular. The modular design allows different modules with different recreational implements to be connected together, and later disconnected and interchanged for other modules. Applicant has thus conceived of a floating playground that supports a variety of recreational implements, is movable and floats. A preferred design concept of the floating playground comprises two modules attached together. Each module rests on a floating vessel and has a frame encircling the perimeter of the vessel. Preferably vertical posts are attached to the frame and support various recreational implements.

[0048] Referring now to FIG. 1, there is shown a perspective view of two modules 11 attached together to form the floating playground generally at 10. A module 11 can be any size, but preferably is no more than eight and one half feet wide, such that the module 11 can fit on a trailer and be transported without a permit. Preferably, the module 11 is supported by a floating vessel 12 that provides buoyancy to the module 11. The vessels 12 are preferably rectangular in shape, made from rotationally molded plastic and filled with foam, or expanded polystyrene, for buoyancy. The expanded polystyrene preferably has a density of 1 lb/ft³. The foam prevents the vessels 12 from filling with water in the event that the plastic shell of the vessel 12 is breached. Referring now to FIG. 1A, there is shown a breakaway, perspective view of one of the vessels 12 shown in FIG. 1. A ledge 14 is molded into the vessel 12 and preferably circumscribes the entire upper perimeter of the vessel 12. The ledge 14 defines an upper portion 16 and a lower portion 18 of the vessel 12. Four pockets 20, or slots, are molded in the upper portion 16 of the vessel 12. The pockets 20 are preferably located just above the ledge 14 with two pockets 20 residing on each longitudinal edge of the vessel 12 near the ends.

[0049] Referring again to FIG. 1, the ledge 14 receives a frame 22 that is preferably made of metal. The frame could also be made of any suitable material to those skilled in the art. The frame 22 is preferably a hollow member, with a rectangular cross-section. The frame 22 circumscribes one vessel 12. Referring now to FIG. 1B, there is shown a partial, cross-sectional view of one of the modules 11 shown in FIG. 1. After the frame 22 is placed on the ledge 14, an attachment means 24, preferably an angle iron made of metal, with a first portion 24 a and a second portion 24 b is slid into each of the four pockets 20. The attachment means 24 could be any other suitable device, made of a suitable material to those skilled in the art, depending on the type of material used to make the frame 22. The attachment means 24 is positioned such that the first portion 24 a slides into the pocket 20 and the second portion 24 b rests flush against the frame 22. The second portion 24 b of the attachment means 24 is then attached to the frame 22, preferably by welding. The attachment of the frame 22 to the four attachment means 24 securely attaches the frame 22 to the vessel 12. Referring again to FIG. 1, a preferably vertical post 28 attaches to the frame 22, preferably by welding. The posts 28 are preferably made of metal, but can be made of any other suitable material used to make the frame 22. The posts 28 can be placed anywhere on the frame 22 in a manner to support any type of recreational implement (not shown).

[0050] Referring now to FIG. 1C, there is shown a bottom view of one of the vessels 12 as shown in FIG. 1. The vessels 12 preferably have three ridges 26, or rudder-like projections, that run the majority of the longitudinal length of the bottom of the vessel 12. The ridges 26 act as rudders when the vessel 12 is moved through the water.

[0051] Referring now to FIG. 2, there is shown a top view of two frames 22 and two flotation vessels 12 of the two modules 11 shown in FIG. 1. A frame 22 circumscribes each vessel 12. The frame 22 is attached to the vessels 12 with the attachment means 24 (shown with dotted lines), which reside in the pockets 20 (shown generally with brackets).

[0052] Referring to FIG. 3, there is shown a perspective view of a preferred embodiment of the floating playground 10. The embodiment shows two modules 11 a and 11 b with various recreational implements attached. Module 11 a is attached to module 11 b with an attachment means 44. Referring to FIG. 3A, there is shown a partial, break away view of the attachment means 44 shown in FIG. 3. The attachment means 44 is preferably a hinge pin assembly 45. The assembly 45 comprises a pair of barrel hinges 45 a and 45 b, and a hinge pin 45 c. The barrel hinges 45 a and 45 b are preferably made of metal, and are attached to the frame 22 of the two modules 11 a and 11 b, preferably by a weld 47. Barrel hinge 45 a is a center hinge 45 a, attached to the frame 22 of module 11 a while hinge 45 b are top and bottom barrel hinges 45 b attached to the frame 22 of module 11 b. The modules 11 a and 11 b are together by bringing the two modules 11 a and 11 b together, then positioning module 11 a such that the center barrel hinge 45 a resides between the top and bottom barrel hinges 45 b. Once the center barrel hinge 45 a resides between the top and bottom barrel hinges 45 b, the hinge pin 45 c is slidably inserted through the top hinge 45 b, through the center hinge 45 a and then through bottom hinge 45 b. The process is repeated for the other attachment means 44 on the modules 11 a and 11 b, and then said modules 11 a and 11 b are connected together to form a floating playground 10. The attachment means 44 is preferably a hinge pin assembly 45, but can also be a latch, a clamp, a U-joint which allows two degrees of movement, but not torsional movement, a spherical end joint which allows three degrees of movement, or any other suitable means to those skilled in the art.

[0053] Referring again to FIG. 3, a floating vessel 12 is shown supporting each module 11 as a buoyancy base. The frames 22 are shown circumscribing the vessels 12. Preferably vertical posts 28 are shown supporting an upper deck 30 on one module 11 a while preferably vertical posts 28 support a trampoline 38 on the second module 11 b. In an alternative embodiment, the space 25 residing between the trampoline 38 and the frames 22 can be surrounded with a safety net (not shown), preferably around all sides of the trampoline 38, to prevent any injury to a user of the trampoline 38. The upper deck 30 comprises a platform 30 a, which rests on a plurality of cross-members 30 b. The cross-members 30 b are preferably made of the same material as the frame 22 and posts 28, and are attached by welding. The cross-members 30 b are supported by the preferably vertical posts 28. A lower decks 32 is shown covering the vessel 12 of module 11 a. The lower decks 32 is a protective covering, known to those skilled in the art, that functions to cover and protect the top of the vessel 12. The upper deck 30 of module 11 a also has a railing 36 attached to the cross members 30 b of the upper deck 30. Alternatively, the railing 36 can be attached to the preferably vertical posts 28. A slide 34 is attached to the railing 36 on the upper deck 30 and runs into the water. The slide 34 is supported by a slide attachment bracket 50 which attaches the slide 34 to the frame 22. A climbing net 46 is attached to the railing 36 and extends into the water. A basket ball hoop 48 is also attached to the railing 36. The trampoline 38 is supported by preferably vertical posts 28. Two ladders 40 a and 40 b are shown on the two modules 11 a and 11 b, respectively. Ladder 40 b extends from the trampoline 38 to the frame 22 and the other ladder 40 a extends from the back side of the upper deck 30 to the lower deck 32 beneath the upper deck 30. The end 42 of the flotation vessel 12 of module 11 b beveled. The beveled end 42 allows the floating playground 10 to glide across the water when the modules 11 a and 11 b are moved across the water. Ridges 26 act as rudders and help to prevent side to side movement of the modules 11 when the modules 11 are being moved. Movement is accomplished by attaching a rope (not shown) to the modules 11 and towing the modules 11 with a boat (not shown), or other suitable water craft. Alternatively, an outboard motor (not shown) can be attached to the module 11 a on the end opposite the beveled end 42 to make the modules 11 self-propelling.

[0054] It will be appreciated that the recreational implements shown in FIG. 3 are illustrative of a few of the recreational implements that can be attached to the modules 11. In addition to the implements shown in FIG. 3, other implements that cab be attached to the playground include, but are not limited to: a swing, a bathroom, a kitchen, curtains enclosing the deck, a canopy covering the deck, a tent covering the trampoline, an infant swing, an inflatable plastic log, a toy captains wheel, a toy periscope, a glass bottom section, a variety of floating toys for children, a set of monkey bars, a jungle gym, a climbing tube, a walk way or any other recreational implement.

[0055] Referring to FIG. 3B, there is shown an alternative embodiment of one module 11 of the floating playground 10. This embodiment shows a circular flotation vessel 12 a supporting a circular trampoline 38 a. The circular flotation vessel 12 a is preferably rotationally molded plastic filled with foam with an opening 17 in the center to form a doughnut shape. In the circular embodiment, a frame 22 a is used to attach preferably vertical posts 28 a to the trampoline 38 a. A ladder 41 is attached to the frame 22 a and trampoline 38 a to provide access to the trampoline 38 a.

[0056] Referring to FIG. 4, there is shown a top view of the preferred embodiment of the floating playground shown in FIG. 3. The two modules 11 a and 11 b are connected together with the attachment means 44. Module 11 b is a trampoline 38. Module 11 a is an upper deck 30 with a slide 34, climbing net 46, ladder 40 and a basketball hoop 48.

[0057] Referring now to FIG. 4A and 4B, there is shown a side view of the module 11 a shown in FIG. 4, with the upper deck 30 and the lower deck 32. The slide 34 is attached as a recreational implement. FIG. 4A shows the slide 34 in a storage or moving position while FIG. 4B shows the slide 34 in a playing position. The slide 34 attaches to the frame 22 with a slide attachment bracket 50 and a pivot hinge 52. The slide attachment bracket 50 is attached to the slide 34 in a manner to those skilled in the art that allows the slide attachment bracket 50 to pivot on the slide 34. The slide 34 can move from a playing position as shown in FIG. 4B to a storage position as shown in FIG. 4A. The top of the slide 34 is detachably attached to the railing 36 a on the upper deck 30 as shown in FIG. 4B. After the slide 34 is detached from the railing 36 a, the slide 34 is moved in an upward direction as indicated by the arrows in FIG. 4B and the slide attachment bracket 50 pivots on the pivot hinge 52. The slide 34 is then attached to the upper railing 36 b in a manner to those skilled in the art to prevent the slide 34 from moving in a downward direction when the module 11 a is stored or moved.

[0058] As indicated above, the floating playground 10 is modular in design. The modular design allows different modules 11 with various recreational implements to be interconnected and form an almost endless array of combinations. Referring now to FIG. 5A, there is shown a top view of a floating playground 10. The floating playground 10, comprises eight modules 11 c-j configured in two rows. The first row consists of modules 11 c-f and the second row consists of modules 11 g-j. The various modules 11 are held together through the use of the attachment means 44. A horizontal ladder 54 is connected to floating modules 11 d and 11 h. A swing support 56 a is connected to floating modules 11 c and 11 g and another swing support 56 b is connected to floating modules 11 f and 11 j. A swinging bridge 58 connects floating modules 11 e and 11 i. Floating modules 11 c, 11 f, 11 g and 11 j have trampolines 38 while floating modules 11 d, 11 e, 11 h and 11 i have upper decks 30 and lower decks 32.

[0059] Referring now to FIG. 5B, there is shown a side view of the eight floating modules 11 c-j as shown in FIG. 5A. The flotation vessels 12 are shown. The frame 22 attached to the flotation vessels 12 is also shown. Preferably vertical posts 28 are shown supporting the trampolines 38, the upper decks 30 and the lower decks 32. Railings 36 are also on the upper decks 30. The swing supports 56 are supported on either end by the floating modules 11 c and 11 g, and 11 f and 11 j, respectively. The swing supports 56 support swings 60. The climbing nets 46 are also shown and supported at the bottom by net supports 62. The slides 34 are shown in the playing position and supported by the slide attachment brackets 50. This arrangement of floating modules 11 and the various recreational implements attached is an example of the number of different embodiments that the floating modules 11 can create. It will be appreciated to those skilled in the art that the modules 11 can be connected to other modules 11 in any configuration or arrangement.

[0060] Referring to FIG. 6, there is shown another alternative embodiment of two floating modules 11 h and 11 i. Module 11 h is shown with a trampoline 38, while module 11 i is shown with an upper deck 30 with various attachments. Attached to the upper deck 30 is a railing 36. A slide 34 is attached to the railing 36, as well as a climbing net 38, a basket ball hoop 48, a climbing wall 62, an accessory bracket 64 and a swing 60 suspended from the accessory bracket 64. The two modules 11 h and 11 i are attached together by attachment means 44. The accessory bracket 64 can be used to suspend or attach any suitable recreational implement to those skilled in the art.

[0061] Referring to FIG. 7, there is shown a perspective view of another alternative embodiment of an arrangement of the modules 11. Module 11 j is shown with a trampoline 38 while module 11 k is shown with an upper deck 30, a lower deck 32 and various recreational implements. The railing 36 of module 11 k supports a basket ball hoop 48, ladders 40, a slide 34 and a climbing wall 62. The climbing wall 62 comprises an upwardly-extending and preferably vertical wall 66 with numerous hand holds 68. The climbing wall 62 can also be tilted away from the module 11 k in to make climbing more challenging. The hand holds 68 can be either rock-like projections or recesses where a user can grasp on to the climbing wall 66. The two modules 11 j and 11 k are connected together with a jungle gym 76. The jungle gym 76 attaches to the modules 11 j and 11 k using the attachment means 44. The attachment means 44 can be a hinge pin, a U-joint, or a spherical end joint. A preferred embodiment of the ladder 54 is to attach it such that the attachment means 44 at one of the opposing ends of the ladder 54 is a U-joint, and the attachment means 44 at the other opposing end of said ladder is a spherical end joint, to prevent the end supported by a U-joint from engaging in torsional movement, and thereby prevent the ladder 54 from spinning about its longitudinal axis. Cross tension members 78 are attached diagonally to the corners of the jungle gym 76 to prevent the modules 11 j and 11 k from racking in opposite directions in an accordion-like fashion. The jungle gym 76 has a horizontal ladder 54 attached to the front side, from which a climbing rope 70 and a swinging disk 72 are suspended. A swing 60 and a trapeze bar 74 are suspended from the back side of the jungle gym 76. There are also two walking ramps 80 that connect module 11 j to module 11 k.

[0062] Referring now to FIG. 8, there is shown a top view of another alternative embodiment of an arrangement of the floating modules 11 to form another floating playground 10. In this embodiment, modules 11 l, 11 m, 11 o and 11 p are trampolines 38. Module 11 n is an upper deck 30. The five modules 11 l-11 o are all interconnected with the attachment means 44.

[0063] Referring now to FIG. 9A, there is shown a side, cross sectional view of an alternative embodiment of the floating module 11. The cross sectional view shows the ledge 14 and one of the ridges 26 attached to the bottom of the vessel 12. In this embodiment, a glass box 82 filled with argon, to prevent condensation, is attached to the vessel 12. A protruding ledge 83 is molded into the top surface of the vessel 12 and surrounds the upper perimeter of a void 84 where the glass box 82 resides. The glass box 82 rests against the lower surface of the protruding ledge 83. The glass box 82 is supported on the lower surface by brackets 85, which are attached to the bottom of the vessel 12 with bolts 87. The bolts 87 threadably engage with bolt mounts 89, wherein said bolt mounts 89 are embedded in the lower surface of the vessel 12. The glass box 82 allows users of the module 10 to view the underwater world. The glass box 82 could also be any other transparent element known to those skilled in the art. Referring now to FIG. 9B, there is shown a top view of the alternative embodiment of the module 11 q as shown in FIG. 9A. In an alternative embodiment, a trap door 86 could attached to the vessel 12 directly above the transparent element 82 and can be opened or closed to either allow or deny access to the transparent element 82. The trap door 86 can also be transparent so users can peer through both the trap door 86 and transparent element 82 if desired. The trap door 86 is shown in an open position and can swing back to a closed position with the use of a trap door hinge 88. The open trap door 86 provides access to the transparent element 82, so that users can see through the element 82 and into the water where the fish 90 are located.

[0064] It will be appreciated that the structure and apparatus disclosed herein is merely one example of a means for floating playground, and it should be appreciated that any structure, apparatus or system for a floating playground which performs functions the same as, or equivalent to, those disclosed herein are intended to fall within the scope of a means for a floating playground, including those structures, apparatus or systems for a floating playground which are presently known, or which may become available in the future. Anything which functions the same as, or equivalently to, a means for a floating playground falls within the scope of this element.

[0065] In accordance with the features and combinations described above, a preferred design of the floating playground 10 includes:

[0066] (a) two modules 11 a and 11 b, each supported by a floating vessel 12, wherein module 11 a supports an upper deck 30 and module 11 b supports a trampoline 38; and

[0067] (b) wherein a railing 36 is attached to the upper deck 30 of module 11 a, such that said railing 36 supports a slide 34, a climbing net 38, a basketball hoop 48 and a ladder 40 a.

[0068] Applicant has discovered that many recreational activities can be done in the water. Applicant has thus invented a floating, modular playground 10 that can accommodate a variety of recreational equipment. Applicant's floating playground 10 comprises a floating vessel 12 that is designed to support any one of an endless array of recreational implement. In addition, applicant's floating playground 10 is modular so that many modules 11 can be connected together to form a floating playground 10.

[0069] Applicant's floating playground 10 can include, but is not limited to, a trampoline 38, deck 30, slide 34, climbing wall 62, swing 60, jungle gym 76, ladders 40, climbing net 38, basketball hoop 48, transparent element 82, and climbing tube to name a few. Applicant's floating playground is supported by a durable, foam filled, plastic vessels 12 that do not require inflating. The foam also ensures that if the vessel were to be damaged, the vessel 12 will not fill with water and retain its buoyancy.
